The demands of heat treatment industry are for higher temperatures, lower pressures, rapid heating and cooling capabilities, and higher production rates.  This has inevitably led to the use of so-called “cold-wall” vacuum furnaces, to the detriment of hot-wall furnaces, which are now considered obsolete. So, let’s see hot-wall and cold-wall furnaces - what could these be and how do they differ from each other?

Advanced engineering components require not only better materials but also new joining or welding processes. Recently, diffusion bonding has become a viable process in the fabrication of structural hardware or fluid and gas flow devices for aerospace and electronic industries. This technology heats and applies pressure on joint materials and uses molecular diffusion to bond them. This means that the resulting joint has properties similar or equal to the parent materials. The process has the ability to produce high quality titanium joints so that neither metallurgical discontinuities nor porosity exist across the interface.

Due to the extreme operating conditions and stringent safety requirements, there is a strong demand for flawless brazed components. Vacuum furnaces allow you to produce leak-tight joints and bright assemblies.

But why they are being considered the best choice for brazing?
Which factors influence the quality and strength of brazed joints?
What risks might you face caused by an excess of magnesium?
